RANGE INCREASES ITS STAKE IN THE EAST COTTON VALLEY PROSPECT TO 21.75%

Range Resources Limited ("Range" or "the Company") is pleased to announce that
it has acquired an additional 8.1875% working interest in its East Texas Cotton
Valley project for a total of $148,000 in lease acquisition costs and an
overriding royalty retained by the seller.

Range's participating interest in the shallow oil project now totals 21.75%.
The acquisition represents an opportunistic additional investment in the
prospect as Range and its partners prepare to spud the Ross 3H horizontal
appraisal well in the coming weeks. The well will be the Company's first in the
project area. The acquisition is expected to provide an immediate increase to
the Company's oil reserves, such increase to be reported at a later date.

The Company's managing director Pete Landau added, "Increasing our interest in
this shallow oil appraisal and development project just prior to spudding the
next well makes good strategic sense for Range and adds oil reserves in a
period of strong crude oil prices. Overall, the project is expected to be an
excellent complement to our North Chapman Ranch interests and should result in
additional production and cash flow in the near term."

Yours faithfully


Peter Landau

Executive Director
